Settings marked with a not applicable label indicate that the setting(s) do not synchronize with AWS. If, however, a zone is assigned to both an AWS Third-party DNS provider and a BloxOne DDI hostUniversal DDI NIOS-X Server, setting(s) changes in that zone are still applicable to the BloxOne DDI hostUniversal DDI NIOS-X Server.
Zone settings
Most of the zone settings are synchronized with Route53 (Refresh, Retry, Expire, Default TTL, Negative-caching TTL, Email Address (For SOA RNAME field)). The exceptions are:
Primary Name Server (For SOA MNAME Field)
Use default forwarders to resolve queries for delegated subzones.
Records
Resource record TTL is inheritable and synchronized with Route53. Therefore, any changes to the TTL value directly on the record or in the inheritance chain will be *synced to Route53. The serial number of the SOA record is not a syncable field. Any changes made to the SN of the SOA record, whether it be due to an edit change or a natural increment due to zone-related changes, are not synchronized to Route53.
